Android: S-22's unpaired server from AppBuildInfo.releaseServerUrl (D-122)

AppBuildInfo gains releaseServerUrl, which :app fills from RELEASE_SERVER_URL (https://<kvitt.publicHost>:8443,
D-121). AboutRepositoryImpl shows it while no server is paired, in place of DataModule.DEFAULT_SERVER_URL, which
is deleted: :data no longer names a host. The fakes' AboutState uses the fixture https://kvitt.example.org:8443;
30 S-21/S-22 goldens re-recorded (only the host changed; oxipng -o 4 --strip safe). New test: unpaired About shows
the release server.
